i've had similar things with mushrooms. did it once (well twice, but u can count out the 1st one), and had a really bad trip, cos i wanted to be tough, and ate the full portion in 10 mins. i'd been pulling myself down for the next 10 hrs, and regretting the whole thing, being laughed at by some of me mates, except for one girl - i dunno what would've happened if she hadn't been there at that time.
i was at a festival, Paasrock, ate the stuff and got mad got emotionally chucked up and down all the bloody time. i had a feeling ppl were looking at me from a distance, in a circular form and with full of scorn. i was biting and eating off every inch of nail on me fingers back then. i felt so low...
other ppl i saw (a huge mosh pit) i regarded as a big fucking swarm of bees. it scared the shit out of me. i saw ppl in 5 different colours in a row - christ i hated myself for it.
i told me dad, and he just reacted disappointed, and hugged me. that's it.
